I agree that diversification is for those who do not know what they are doing, or those who have a lot of money to play with. I just wrote about Warren Buffett's wisdom on investing recently and while I was doing my research on him I found out that he is not a great fan of diversification. I think his mindset is that if you are investing in a lot of different things then you are doing so blindly, because most people don't have the time to really dive deep into many different cryptos/financial assets.
Anyways, I followed you because I found this to be really good information and I hope you will post more in the future!
